I have a Williams wall furnace that has decided not to turn off by either the thermocouple of the temperature setting knob. Could this be a malfunction in the gas valve or should I consider checking the T/C. This is my first attempt at fixing a furnace so any help would be greatly appreciated. The number under the valve are P322051, JO125149, 10-LR and 6-1995 all in different locations. Could you advise as to where to purchase replacement parts in California or the Internet?
Thanks
Thanks

Hello: rogie66. Welcome to my Gas Appliances Forum Topic and our Do It Yourself web site.
If I understand the problem as you are describing it, removing the thermostat leads and the pilot generator leads, either or both, the burner still does not shut down? Is this correct?
Simple tests. Disconnect the leads on the gas control valve from the thermostat and note what happens. The burner should shut down. If not, the problem is not the thermostat.
If the burner does shut down, the thermostat and or the wiring connecting the T-Stat at the wall or any part of the wiring between the T-Stat to the gas control valve is defective.
Defective meaning shorted somewhere. Next step would be to reattach the wires to the gas control valve. Disconnect them at the T-Stat and note the results.
If the burner shuts down, the T-Stat is defective. If the burner remains on, meaning the flames are still present from the burner, the wires between the wall and the gas control valve are shorted.
If no T-Stat wires are connected to the gas valve and the burner remains on, also disconnect the pilot generator leads and note what happens. The burner should shut down.
In both cases, the meaning of pilot generator (PG) will be the same as a thermocouple (TC). Does not matter which. The pont is if all connections to the gas valve are removed and the burner remains on, it can than be safely assumed the gas valve is not shutting down.
In both cases, T-Stat wires removed and or the TC or PG removed, the gas valve is defective. Also dangerous, since the internal safety device is not shutting down as it should.
In that case, gas valve replacement is the only safe solution. One can be purchased at any heating parts supply store or most appliance parts stores. All listed in your local areas phone book.
Be advised that any gas valve, propane or natural gas, that has the condition you're describing in any fashion or way is potentially dangerous. It must be replaced to insure safe operation.
Retail parts dealers can also help determine what the possible problem may be. Bring the make, model and serial numbers if you stop in at the store. The info will help to determine the possible problem causes.
Be sure the appliance is turned off before attempting any repairs. Always check for gas leaks whenever a repair includes any connection of a gas part, gas line or tubing or gas supply.
If you need further assistance, use the reply button to add any additional information or questions, etc. Using this method also moves the topic back up to the top of the list automatically.
Kindly post back the results of the tests. Also the final solution. Doing so allows me to be sure your safe and all other members reading your question to learn more.
